SPECIFICATION forming part of Letters Patent No. 398,959, dated March 5, 1889.

Application filed jtcnib'. l, 1888. Serial No. 284,351. (No model.)

To all 'IH/.0m 'it muy concern:

l-le it lknown that l, CHARLES Il. GAGE, of the town of l'ielnnond, in Walworth county, and State of \\'isconsin, have invented a. new and useful. improvement in (llultivators, oli which the following isa specification.

This invention relates to that class ol cultivators known as sullty or riding cultivators designed. to cultivate both sides of a row et' corn at the saine time.

The object of my invention is to produce a eultivator so constructed as to have an easy lateral as well as vert-ical movement of the teeth, which can be readily guided while in use by the feet of the operator sitting on the seat, thereby controlling the teeth and conforming the urrowmadebyeaeh to the slope ot the row being cultivatedwithout changing their adjustment to the machine, and at the saine time to have each tooth maintain its relative angle with the line et' draft, as well as other iinprovem ents, hereinafter described, all of which constitute the subject-matter et my invention.

In the accompanying drawings, Figure l represents a side elevation ot' a wheel-cultivaior embodying my invention, the forward part of the tongue being broken away. Fig. :l represents a plan view of the drag-bars and the parts attached. Fig. El represents a detail front elevation ot' the arched hanger and the device for attaching the drag-bars thereto. Fig. l represents a plan view oi" the axle, the tongue, and said hanger. Fig. 5 represents a 'front elevation ot' the axle, its journals, and the brace l." for the drag-bars, the lower part ot said brace being broken away. Figs. G, 7, S, .l, l0, and ll represent detail views of the devices for attaching' a shovel or coltivatortooth to one oil' the drag-lmrs, Fig. l() showing the tooth or shovel also, and YFig. lll only the tapering plug.

Similarlettcrs re'ier to similar parts throughout the drawings.

A .represents the wheel of the cultivator; B, the axle, with its arms l) I), upon which the wheel A revolves.

C C represents the tongue, made of two pieces oli' wood coming together at the front ends, the rear being' spread apart and bolted to the axle ll.

D D represent the two pieces of timber upon which the seat. \V is secured, the Yfront ends of these seat-pieces being bolted to the prongs ot' the tongue in lronl o. the axle, extending back across the top ot the axle a distance sufficient to allow the seat to be in the proper position. over the drag-bars.

E represents the lever, which operates with the ratchet K, and being pivoted to it by the bolt d and connected at its forward end to the drag-bars by the rod L, which hooks into the eyebolt m in the front end of the lever, and alsohoolts into the hole d in the cross-plate g. This lever is used for raising and lowering the drag-bars, the handle ot' said lever being in the rear of the axle and in convenient reach ot the operator.

F represents a brace, as shown in Fig. l, which slides through, and is held in place by the loops o vo on the rear side of the axle l, as shown in Fig. '7, the lower ends of which drop down and pass through the holes 7e 7L in the erossplate on top oli' the dragbars The office of this brace l? is to regulate. the dragbars on each side ot' the row being cultivated.

G represents a rod or brace bent in the form of a crank at each end, as shown in Fig. 2l. Its shaft part lies across the top of the tongue, as shown in Fig. 5, and is fastened to the said tongue on each side by the hasps q q. The crank ends of this brace drop down and pass through the holej in. the device ll'7 as shown in said ligure. The ends project. through far enough that they may take on them the front end of the brace l, as shown in lig. l, the brace being held at its front end by a nut which is screwed onto the end et the brace G, and at its rear end by a bolt passing through it and the axle, as shown in Fig. l. The office performed by this brace G Yis not only to securely hold the device ll in position, but also to Yfornia pivot or joint, on which. the dragbars, when attached to said device ll, can turn either up or down, and thus contorni to the uneven surface ol.A the land being cultiifated.

ll represents the device for holding the front ends et' the drag-bars, as shown in Fig. 2. It made ot' iron, and at each end there is a hole to receive the bolt i, which secures the front end of lthe drag-bar to the device. On the top ot' this device there is a brace, (l,

IOO

eration, may conform readily and easily to the zigzag direction of the rows without chan g ing the course of the team. On the front side of this device H isa protrusion extending from the center of the front side thereof far enough to enable the large hole j to run through it parallel with the device. lt is this hole j and the lower end of the crank-shaped brace G when it is put through it that form the pivot upon which the drag-bars have their upward and downward movement, and Wh ich permit the drag-bars to conform to the uneven surface of the land being cultivated, and permit the wheels to drop'into the low places and to rise on the high places without affecting the running depth of the shovels.

M represents the front end of the drag-bar, and N the rear end. rlhcse are wood, and are nearly of the same length, being lapped together about eight inches and secured by the bolt T,the front end of the rear piece, N, being under the rear end of the front piece, M, and having a brace, P, from its lower side extending up and bolted to M, and a brace, fr, from the upper side of M down to the upper side of the piece N, and securely bolted in position by the pivoted bolt T, as shown in Fig. l. The front end of M is bolted to the device ll by the bolt t' and braced by the brace O, as described. Attached to the rear end of the piece N are two shovels, being fastened thereto, as hereinafter described, the rear shovel being attached to the outside and the front shovel being attached to the -inside of the piece N, as shown in Fig. l. The drag'- bar thus formed, it'will be seen, has two pivoted points-one in the center and one at the frontend. These pivoted points provide for the lateral movement either way of the dragbars, and also of the shovelsattached thereto, without changing the line of draft, and, if desired by the operator, the furrows made at the same time conform to the shape of the row being cultivated.

There are four drag-bz-Lrs-two on each side of the cultivator-all made of similar material and in the saine manner, and are attached to the other parts of the cultivator in the saine way, and on each of the drag-bars are two shovels. Back of the pivoted center of each drag-bar is a plate of iron, g, extending from one drag-bar to the other and bolted to the top of each in such a way as to hold the drag-bars parallel with each other, and on the front edge of this plate g is a hole, a, for receiving the lower end of the rod, attached to the end of t-he hoisting-lever E, to which it is secured, and by which the drag-bars are raised and lowered, while in the center of this plate g are holes L, into which the end of the rectangular brace F, Fig. 4, is inserted. This brace keeps the two sets of drag-bars a uniform distance apart when in use, the upper side of the brace sliding through the staples e yr, fastened to the rear side of the axle B. Still farther back, and between the shovels and on the top of the drag-bars, is another iron plate, at, extending from one drag-bar to the other, which is securely bolted to each drag-bar, and to this iron plate is securely bolted the foot-rest S, as shown in- Fig. 2. The driver, while seated in the seat, by placing his foot on the foot-rest S, can gage the furrows made by the shovels so as to have them near to or remote from the row being cultivated, while at the same time the main furrows will be parallel with the line of draft of the machine.

Figs. 6, 7, S, and 9 show different sides of the same piece of cast-iron. In these drawings, A represents a piece of castor malleable iron with anges e e on each side and a large round hole, through its center, the piece A being from one to one and a half inch in thickness. This hole 0c is tapering, being larger on the outside, as shown in Fig. 9, and smaller on the inside, as shown in Fig. 7. Into this hole is inserted the corresponding tapering pin, B', which is also made of metal, provided with a recess, d', at its largest end for the shaft of the shovel D to set into, and a round hole, c', through its center, so that when A is placed again st the side of the dragbar the flanges e e projecting over each side, and B is inserted into t-he hole cr in A', and the shovel-shaft D', with a hole through its top end, is laid into the recess d', and a bolt is put through the hole in D and through the hole c in l and through the drag-bar N, and the nut is screwed down sufficiently tight, a device is formed for holding in position to the side of the-drag-bar the shovel of said cultivator, so that when the tooth or shovel meets an obstruction of sufficient resistance the shovel of said cultivator will turn back, and the shovel will pass over said obstruction without breaking or injuring any part of said cultivator. After said obstruction is passed, the device and shovel can be readily and easily adjusted and the machine proceed as before.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is as follows:

l. A set of cultivator drag-bars, each made in two sections jointed end to end for lateral vibration, in combination with couplings which connect the parallel sections in pairs, braces extending from each forward section to the rear section of the same drag-bar, a cultivator-frame, and a hanger which suspends said drag-bars from said frame, but allows vertical vibration, substantially as set forth.
